COMBINED HARROW, CLOD-CRUSHER, AND LAND-ROLLER SPECIFICATION formig gpart of Letters Patent No. 376,841, dated January 24, 18 88. Applicationfiled August 18, 1887. Serial No. 247,252. (hlo model.) l v To aIZZ whomit may concern:

Be it known that I, GEORGE W. ALBAUGH, a citizen of the United States,and a resident of State Line,in the county of Franklin and State oI'Pennsylvania, have invented certain new and useful Improvementsin aCombined Harrow, Clod-Orusher and Land-Roller; and Ido hereby declarethat the following -is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, and inwhich Figurel is a side view of myimproved combined harrow,clod-crusher, and land-roller. Fig. 2 is a longitudinal verticalsectional view of the same. Fig. 3 is a transverse vertical sectionalview takenon line we in Fig. 1. Fig. 4 is a top plan view; and Fig. 5 isa detail perspective view of one of the brackets and one of the wheelsor rollers of the pivoted frame. Likeletters of reference denotecorresponding parts in all the figures. r

My invention has relation'to that class of inventions known as combinedharrows, clodcrushers, and land-rollers, and it consists in theconstruction and combination of parts of the same, as will behereinafter more fully described and claimed.

In the accompanying drawings, the letter A platform, D, secured thereto.BracketsE EE project downwardly from the rear end of the main frame, andare formed with bearings at their lower ends to receive the trunnions oftwo land-rollers, F F. V

A transverse frame, G, is pivoted upon a king-bolt, G, under the forwardend of the main frame, and has brackets 'H H H, similar to those securedto the rear end ofthe main frame, projecting downwardly. The trunnions II of the clod-crushers IIarejournaled in the lower ends of thesebrackets,to the outer ones of which are secured outwardly-projectingscrew-threaded bolts J J, to which two longitudinally-slotted bars KKare adj ustably secured by means of thumb-nuts L L. The

the slots in the bars and serve to keep the said bars in a verticalposition. To the lower ends of these slotted bars, which are providedwith stub-axles M M, are j-ournaled wheels or rollers N N, adapted'totravel upon the ground.

trunnions of the clod-crushers project through To the forward end of theframe G are piv-:

oted the rearwardly diverging hounds 0, to which the tongue P, carryingthe doubletree- Q, is attached.

Two or moreharrow-beams, R R, hingedtogether at their sides and havingteeth, preferably inclinedrearwardly in their under'sides, are attachedto the hooksQ Q upon the rear side of the doubletree Q by means ofchains rear one of these barrow-beams has a chain, T,

means of a rod, d, to a lever, U, fulcrumed S S,'secured to the forwardbarrow-beam. The

upon the main frame, the said lever being adapted to raise and lower thebarrow-beams y when desired,and to retain them in theirraised or loweredposition by, means of the catch U, upon the free end of the leverengagingthe teeth upon segment-rack V, which is se cured to the platformof the main frame near the drivers seat W, so as to enable the driver toeasily adjust the lever in the said segmentrack- 80 Balls X X aresecured upon the central cross-piece of the main frame,andreceivebars YY,having vertical apertures ZZ. in their free ends communicating withapertures a c at right angles-to,the vertical apertures.

. 5 b 1; denote the markers, having curved flattened lower ends, and aresecured in the bars It will be seenthat by having theadjustable bars,with wheels journaled thereto,the crusher-rollers may be raisedor'lowered according] to the condition of the ground, andwhen theimplement is transported from one placeto another the wheels orrollersare lowered sufficiently to allow the pressure-rollers to pass over theground without coming in contact with the same.

It will further be seen that by havlng the harrow supported'by thechains connected to v the doubletree and to the lever the harrow mayrockto either side, and will follow any unevenness of the ground,or, ifdesired,it may be raised from contact with the ground by means of theoperating-lever.

The implement will first harrow the ground, whereupon thecrusher-rollers will crush any clods which were not broken by theharrow, and at last the land-rollers will smooth the ground,leaving itperfectlyprepared for planting. All of these processes will be performedat once without requiring but little more draft than either one of theseparate elements.

Having thus described myinvention,I claim and desire to secureby'Letters Patent of the United States 1. In a combined harrow,clodcrusher, and land-roller, the combination of the main frame havingbrackets in its rear end, land-rollers journaled therein,a pivotedcross-fran1e at its forward end, brackets secured thereto, andclod-crushers journaled in said brackets, with slotted bars formed attheir lower ends with stub-axles, wheels, orrollers journaled upon saidaxles, and means, substantially as described, for adjusting said bars.

2. In a combined harrow, clod-erusher, and landroller, the combinationof the main frame having brackets secured in its rear end, landrollersjournaled in said brackets,brackets secured at its forward end,screw-threaded bolts projecting outwardly therefrom, and cloderushersjournaled in said brackets, wlth slotted bars formed at their lower endswith stubaxles, wheels, or rollers journaled theret0,and thumb-nuts.

3. In a combined harrow, clod-crusher,and land-roller, the combinationof the main frame,

land-rollers journaled in its rear end, a cross frame pivoted to itsforward end, clod-crushers journaled in brackets secured to the saidcross-frame, and markers, substantially as described,secured to the sideof the mainframe, with aharrow consisting of two or more beams havingteeth in their under sides hinged together, the tongue secured to saidcross-frame, a doubletree secured to said tongue, chains connecting saidharrow with said doubletree, and means,substantially as described,forraising and lowering the said harrow.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

GEORGE W. ALBAUGH.
